Description
CATO manufactures 2-(2,5-Dimethylthiophen-3-yl)acetonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
2-(2,5-Dimethylthiophen-3-yl)acetonitrile (CAS 26431-97-0), molecular formula C8H9NS and molecular weight 151.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2,5-Dimethylthiophen-3-yl)acetonitrile (C8H9NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
